My drivers directory refuses to be removed too, but I'm not really fussed about it. There doesn't seem to be a limit on how many batch files you can have, or the commands you have in them. But its unusual that another batch is executed when the previous hasn't finished (my Nero installation forced the next batch to execute and killed off my applications batch, strangely enough!). So, when you said half of the apps were installed and none of the hotfixes installed, this is probably because of two setup processes running at the same time from 2 batch files causing a conflict. Next time, put all 5 of your batch files into one. Someone else will have to help you with 1. and 2.
